A relativistic many-body theory for the electric dipole moment (EDM) of paramagnetic atoms arising from the electric dipole moment of the electron is presented and implemented. The relativisticâ€¦ (More)

The multireference normal order theory, introduced by Kutzelnigg and Mukherjee [J. Chem. Phys. 107, 432 (1997)], is defined explicitly, and an algebraic proof is given for the correspondingâ€¦ (More)

We report the result of our ab initio calculation of the 6s2S1/2-->5d2D3/2 parity nonconserving electric dipole transition amplitude in 137Ba+ based on relativistic coupled-cluster theory.â€¦ (More)

Unconstrained acquisition of data from arbitrary subjects results in facial scans with significant pose variations. The challenges in 3D face recognition are into two main stages, namelyâ€¦ (More)

We present in this paper two new versions of Rayleigh-SchrÃ¶dinger (RS) and the Brillouin-Wigner (BW) state-specific multi-reference perturbative theories (SSMRPT) which stem from our state-specificâ€¦ (More)

One generic difficulty of most state-specific many-body formalisms using the Jeziorski-Monkhorst ansatz: Ïˆ = Î£(Î¼)exp(T(Î¼))|Ï†(Î¼)>c(Î¼) for the wave-operators is the large number of redundant clusterâ€¦ (More)

We present the formulation and the implementation of a spin-free state-specific multi-reference coupled cluster (SSMRCC) theory, realized via the unitary group adapted (UGA) approach, using aâ€¦ (More)

In this paper, we present a comprehensive account of an explicitly spin-free compact state-universal multireference coupled cluster (CC) formalism for computing the state energies of simpleâ€¦ (More)
